I came across roleplaying games through boy scout camp playing dungeons and dragons in the woods by lantern light. Once I returned to civilization my twin brother picked up Alternity, a late 1990s TSR sci-fi rpg, and I volunteered to run our first game - a very blatant rip off of William Gibson's Neuromancer.
The next leg of this adventure came when a friend of a friend told me about a game called Werewolf: the Apocalypse, I played a wereshark my brother played a werespider. At our local gaming store my friends and I spent years making our way through everything white-wolf put out.
Onyx Path and White-Wolf get the lion share of my attention but I've also enjoyed running many other games. Mage the Ascension (Revised & M20), Exalted (3rd), Hunter (the Reckoning & the Vigil), and Vampire (V20 & Requiem 2nd), and Mouse Guard are a few my favorite rpgs.
